Title: Automatic unstacking machine for animal skins - with surface rumbling to admit air between layers to assist sliding of each skin
IPC: B65H3/08
Filed: 1975-01-20
Abstract: Animal skins, or irregular sheets of thin and supple material, are automatically removed from a stack, unit by unit, and placed on a conveyor for transport to the next treatment stage. The unstacking equipment is mounted on supports which carry an intermediate conveyor, driven by the drum; the conveyor has metallic meshes and a vertical shaker operated by the shaft; this is provided with eccentric cams which alternately raise and lower the upper strand. The carriage can move horizontally along the longitudinal girders under the influence of the jacks the piston rod of the latter being fixed to the angle bracket; the piston rod of the former is fixed to the carriage. A longitudinal pusher system is fixed below the carriage: it carries shoes, fitted with rubber teeth, which push the skins, one by one to the conveyor; the movement is assisted by the pince system, operating transversely, and a sucker head, while a probe brings the table to the right height so that the shoes can bear on the top skin in the pile. Sufficient air is introduced mechanically between the top skin and the next in the stack, so that when the moment of transfer arrives the top skin will slide by inself and leave the adjacent skin in the stack. The admission of air is facilitated by the rumpling effect produced by the shoes; this helps to break the various physical bonds between the contact faces of the skins in the stack.

Title: Thin walled vessel or suction pipe under reduced pressure - has compartmented double walls under pure tensile stresses
IPC: B63B35/28
Filed: 1975-10-03
Abstract: The shells of vessels or suction pipes contain a fluid at a lower press. than that of the surroundings and have double walls made of rigid or flexible materials between which the press. is maintained above that of the surroundings. Each wall is divided into adjacent elements so that it assumes a scalloped form under the combined effect of the press. of the fluid between the walls and the restraining forces exerted at the joint edges of the elements. Arrangement allows the selection of the min. value of the press. of the fluid between the walls, to reduce all the stresses exerted in the structure to pure tensile stresses, eliminating bending stresses to which it would not be resistant. The curvature of the elements can be obtd. by construction when rigid materials are used or by inflation when flexible material, e.g. coated textiles or elastic membranes are used. Method provides a structural arrangement for vessels and pipes under reduced press. which gives lightness and flexibility at ll diameters. It also provides the facility of flattening and folding such vessels and pipes for transport and the ability to install them at low cost, e.g. in the case of large low press. chambers or of sea-water suction pipes operating at high rates, and great depths, for aquaculture and exploiting the thermal energy of the seas.
